Building a microscale creation is pretty easy. Just build something small. It can be a tank, a zeppelin, a spaceship, etc.Requirements: at least 1 brick representing a source of propulsion, and at least 1 brick representing a control center.

Upon a gun or the engines being destroyed, roll a D4. The number on that is how many studs the explosion chains to. So if a gun is destroyed, and I roll a 3, the explosion chains to any "explodable" object within 3 studs. Roll another D4 for each object it chains to. If you roll a 1, the explosion stops there. Also, each object getting hit makes it's usual armor value -1 save. If it makes it's armor roll, the chain reaction stops there as well.

MECHA:measure length with height instead (in studs.) (measured using a flat plate held to the side of the mech like a ruler.) After determining size, divide Armor and # of actions by two, rounding down. (This is so mech weapons are actually effective) Minimum armor is 3D6, and minimum # of actions is 3.

Mecha weapons: (Can not be used with regular weapons. Only mecha can have these weapons.)

REMOVING LIMBS:A mecha that has a CC weapon can attack it's opponent, and attempt to sever a limb. Limbs must be composed of more than one brick.Limbs get-1 armor, and the attacker gets -1 skill.Upon a successful attack, the attacker gets to remove a limb from his opponent's mech. (I.E. Arms, legs, jump-packs, etc.)

JUMP-PACKSPretty self-explanatory, a jet-powered way for your mecha to get around. Any mecha with a jump-pack can decide to launch itself using the jump-pack after it has moved, but before it has shot. Jump-Pack:UR: 3upon success, launches user height+1 inch.(IE: 5-stud tall mecha, launches 6")
